Aurora australis

Aurora was the Roman goddess of the dawn (the Greek Eos). The sons of Aurora and the titan Astraeus were the four winds: Boreas, who blows from the north, Notus, the southwest, Eurus, the east, and Zephyrus, the west. The spectacular streaks of light which appear in the sky at night are a result of the effect of the particles of the sun's rays on the upper atmosphere. Seen especially at the poles, in the northern hemisphere they are called the northern lights or the aurora borealis, and in the south, the aurora australis, Auster being the Roman name of the southwest wind.
